What is wrong with my code???

Let's get in some slice practice! Create a new variable named slice1 that has the second, third, and fourth items from favorite_things.

slices.py
favorite_things = ['raindrops on roses', 'whiskers on kittens', 'bright copper kettles',
                   'warm woolen mittens', 'bright paper packages tied up with string',
                   'cream colored ponies', 'crisp apple strudels']
slice1 = favorite_things
slice1 = [1:3]

I believe it needs to be slice1 = favorite_things[1:4]

The second element refers to index 1, third element to index 2, and fourth element to index 3. The slice will include index 1 all the way up to but not including index 4.

I see two issues:

  • the slice numbers in brackets must come directly after the name of the list
  • as Kyle pointed out, the "stop" number is the index to stop before

slice1 = favorite_things[1:4]

Sorry to necro this, but just now going through the program. Maybe this would be helpful to others in the future.

I did the same thing and over-complicated it. I wrote mine as:

slice1 = favorite_things[:] slice1[1:4]

When it really just needed to be "slice1 = favorite_things[1:4]" for the challenge. Although, mine wasn't wrong, it was just less concise with an extra step in there.
